Use the additive relationship to rearrange addition equations

Maths

In this unit pupils will accurately and efficiently solve multi-step addition and subtraction problems. They will understand and explain how both addition and subtraction equations can be used to describe the same additive relationship In the future unit pupils will identify the addends and the sum in column addition They will use their knowledge of place value to correctly lay out column addition

In the prior unit pupils reviewed and secured previous knowledge of adding 3 addends, understanding they could be added in any order, bridging through 10. In this unit pupils will accurately and efficiently solve multi-step addition and subtraction problems. They will understand and explain how both addition and subtraction equations can be used to describe the same additive relationship.
